So far, so ordinary; where things get interesting is the Macally PowerPal's built-in USB connection and iPod/iPhone cable that enables you to charge up your iPhone or iPod without having to take your charger with you.

So with the Macally PowerPal you don't have to carry a separate iPhone or iPod charger with you when you're abroad. And you don't have to keep swapping over the plugs between your iPod charger and other devices. Worth a look.

The Powermonkey-classic V2 from PowerTraveller is a palm-sized portable power charger that can link to a wide bunch of battery-hungry gadgets, including mobile phones, iPods, games consoles, digital cameras and PDAs.
